“…Habitat assessment results here indicate that there was an improvement in the RHI following the exclusion of cattle access, and an increase in ground vegetation cover in riparian areas was observed. Reductions in the extent of bare ground following cattle exclusion via fencing were previously reported in Alberta, Canada by (J. Miller, Chanasyk, et al, 2010) and in the north of Ireland by Rice et al (2021) and were linked to improved water quality (J. Miller, Chanasyk, et al, 2010). These authors also found no improvement in stream bank stability following 4 years of cattle exclusion (similar to the current study) but did suggest that increased ground cover could contribute to reduced rates of stream bank erosion.…”

“…Degradation of freshwater resources with nutrients and sediment as a result of agricultural practices is a key global challenge (EEA, 2015; EPA, 2020; Novotny, 1999; Schulte et al, 2009). Direct cattle access to streams represents a point source of nutrients, sediment and pathogens (Belsky et al, 1999; Bragina et al, 2017; Conroy, Turner, Rymszewicz, O'sullivan, et al, 2016; Davies‐Colley et al, 2004; Godwin & Miner, 1996; Rice et al, 2021). In this study the efficacy of fencing as a means of reducing in‐stream sediment deposition and improving stream ecological quality in both the short and longer term has been demonstrated.…”

“…Increases in limiting nutrients such as phosphorus and nitrogen, as a result of cattle defecation both directly in streams and in the adjacent riparian zone, can lead to concentrations that are detrimental in themselves (Sarriquet et al, 2006), but can also result (in association with reductions in riparian cover/shade) in proliferation of instream algal communities (Braccia & Voshell, 2007). Damage to stream banks by the erosive action of cattle hooves as they enter and exit streams, and as they consume and trample streamside vegetation, contributes significantly to stream-suspended sediment inputs and bed loads of fine sediment (Braccia & Voshell, 2007;O'Sullivan et al, 2019aO'Sullivan et al, , 2019bRanganath et al, 2009;Rice et al, 2021;Schulte et al, 2009;Scrimgeour & Kendall, 2003). Habitat change as a result of algal proliferation and sediment-induced stream bed homogenisation seriously alters macroinvertebrate communities in affected streams (Braccia & Voshell, 2007;Sarriquet et al, 2006;Stone et al, 2005).…”

Headwater streams can constitute up to 80% of river channel length and are vulnerable to anthropogenic pressures due to their high connectivity to adjacent land, large relative catchment size and low dilution capacity. In these environments, unrestricted cattle access is a potentially significant cause of water quality deterioration, resulting from increases in stream bank erosion, riparian damage and sediment deposition among others. Several studies have reported improvements in the physico‐chemical and hydromorphological conditions of streams following the elimination of cattle access; few, however, have focussed on the ecological impacts of such management practices. Here, such impacts are assessed. The study explores the short‐term effects of cattle exclusion by comparing habitat conditions, sediment deposition and instream macroinvertebrate communities upstream and downstream of cattle access points prior to, and 1 year following exclusion via fencing. The long‐term effects are also measured by reassessing a small stream catchment entirely fenced off from cattle access in 2008 under a dedicated management plan. In the short term, cattle exclusion led to a reduction in deposited sediment downstream of cattle access points and a related homogenisation of macroinvertebrate community structure between upstream and downstream of cattle access points. Increased abundances of specific indicator taxa (Ancylus fluviatilis, Glossosomatidae and Elmidae) in the fenced catchment following 9 years of exclusion highlight the long‐term ecological benefits of such mitigation practices. These findings highlight the importance of incentivised agri‐environment measures in reducing the negative impacts of cattle access to vulnerable aquatic ecosystems.

In this paper, we propose a method for instance segmentation of individual grains from a terrestrial laser scanning point cloud representing a mountain river bed. The method was designed as a classification followed by segmentation approach. The binary classification into either points representing river bed or grains is performed using the Random Forest algorithm. The point cloud is classified based only on geometrical features calculated for a local, spherical neighborhood. A multi-size neighborhood approach was used together with the feature selection method that is based on correlation analysis. The final classification was performed using a set of features calculated for the neighborhood size of 5 cm, 15 cm, and 20 cm. The achieved classification results have the overall accuracy of 85% to 95%, depending on the test site. The segmentation is performed using the DBSCAN algorithm in order to cluster the point cloud based on Euclidean distances between points. The performed experiments showed that the proposed method enables us to correctly delineate 67% to 88% of grains, depending on the test site. However, the resulting point cloud-based completeness expressed as Jaccard index is similar for each of the test sites and is approximately 88%. Moreover, the proposed method proved that it is robust to the shadowing effect.
